Easy Asset Supervision

• Permanently mounts on a single transformer oil

valve. No extra piping or pump required

• “Composite gas” sensor responds 100% to

Hydrogen (general fault gas) and is also sensitive

to Carbon Monoxide (overheated paper)

Acetylene (arcing) and Ethylene (overheated oil)

thus covering main failure root causes

• “Hydrogen only” gas sensor is simpler and

responds 100% to Hydrogen gas only, the

general fault gas

Configurable Alarms

• An alarm is raised when an abnormal level of

fault gas is detected

• Two alarm levels (one for Alert and one for Alarm)

can be set to show increasing severity

• Alarms can be set on gas ppm levels or on gas

rate of change (ROC) over an hour or a day

• Automatic self-test every 15 days will trigger

service alarm if it detects a fault, including power

failure, oil valve closed, sensor or  battery needing

replacement
